I'll take it back 60 years. I personally timed Bo Jackson (4.29) and Deion (4.25) and sat 10 yards from the start line when John Ross ran his 4.22. Timed Barry Sanders at 4.38, but Barry ran in tennis shoes and shorts and never warmed up. Just showed up, got to the line, took off https://t.co/RsgGXyNMMs
